O direito à informação jornalística: garantias constitucionais ao direito de ser informado no sistema brasileiro.

The freedom of social communication referred to those freedoms exercised under of the media. The journalism is professional activity responsible for factual information, real, pluralistic and of the public interest, directed diffusely to social orientation. The right of the information, characterized as diffuse right or of fruition by uncertain and numerous holders, is subdivided in the right of the inform, inform yourself and right to be informed. The journalists, as occupants of a enlarged spectrum concerning of right of the inform, have responsibility for the information they disseminate, devoir that puts on the basis of the constitutional right to be informed. This duty is divided with journalistic companies, when them realized. In the research, examined the existence of constitutional guarantees the right to be informed. To answer the question, realized research to support bibliographical and documentary. The guaranty is a empirical preoccupation coated with legality, since lends itself effect concretize a right. Traced so a panel of guarantees of institutional imprint, substantive and procedural. Treating of the institutional guarantees the right to information, it would refer to true institutions (as the free press) and may begin subjective rights. In the case of substantial guarantees, we would have access to information, the confidentiality of the fonts and the incensurable feature of journalistic information. A guarantee peculiar would be constitution of bodies responsible for monitoring the quality of the vehicles of communication. Trace it also a panel strict of procedural safeguards, such as public civil action, the security s warrant, and the rights of petition and answer.

Os crimes de mídia no paradigma democrático constitucional

The criminal responsibility of the media is analyzed when the criteria for production of news and events involving public safety are produced without considering the technical, legal and ethical practice of journalism in the media factors. Freedom of speech, expression of thought, necessary for professional qualifications and constitutional limits, reaching criminal constitutional principles and the possibilities of criminal liability for offenses practiced in the media are present as key factors legal dialogue in this work. The judgment of the Supreme Court on the unconstitutionality of Law nº. 5.250/67 called Media Law caused a gap in the national legal system, forcing the use of the criminal code to address issues that involve crimes produced in media professional performance. The presumption of innocence is ignored by the professional media during a police investigation where the information published does not respect, including constitutional guarantees: the right to privacy, honor and image. The right to information and the duty to inform media are worked in its constitutional aspect, considering that the same information should be produced is guided by the quality and guiding principles of truth. The constitutional concept of media is presented as information with the appropriate language of the news media, produced and disseminated through the vehicles of mass media, whether in print or digital platform. The presented model of the legal right to information is outlined from a constitutional hermeneutics, increasing the production of news as a result of the occupation of journalist in different news platforms, guaranteeing the quality of this prolific law. Under the Freedom of professional activity of the journalist, the constitutional limits are addressed in line with the reality of (non) regulation of their profession, considering the constitutional abuses committed in the exercise of that activity linked to communication fences. Jusphilosophic field reaches the limits of the duty of truth in journalism as a tool for spreading news, respect the audience and compatibility with the constitutional state. Using the conceptual and doctrinal aspects, this criminal offense is parsed from the journalistic practice and the publication of news involving public safety, with the hypothetical field consummation of that crime through the eventual intention. As a form of judgment against these crimes produced in honor media presents the court of the jury as a legitimate form of democratic decision

Qualitative feed restriction for heavy swines: effect on digestibility and weight of organs of digestive tract, and environmental impact of feces

Foram utilizados 50 suínos machos castrados para avaliar o efeito da restrição alimentar qualitativa sobre a digestibilidade dos componentes dietéticos, os órgãos do trato digestório, a composição e a produção fecal. Foram utilizadas cinco dietas experimentais, com níveis de restrição qualitativa de 0, 5, 10, 15 e 20%. Houve redução linear (P<0,001) para todos os coeficientes de digestibilidade, com exceção da fibra em detergente ácido, que apresentou resposta quadrática (P<0,05). Os teores de sólidos totais (P<0,01) e voláteis (P<0,05), e minerais totais (P<0,001) nas fezes aumentaram com os níveis de restrição alimentar, enquanto os níveis de K (P<0,05), Cu (P<0,01) e de N, P, Na, Ca, Mg, Fe e Zn (P<0,001), apresentaram resposta quadrática. A excreção diária de fezes, sólidos totais e voláteis, minerais totais, N, P, K, Mn e Cu (P<0,001), Ca, Na, Mg e Fe (P<0,05) apresentaram aumento em função do nível da restrição alimentar qualitativa. A restrição qualitativa pode ser alternativa para destinação de resíduos da agroindústria, conferindo boas propriedades às fezes suínas, no que diz respeito à utilização para adubação de culturas.

Carcass characteristics and meat quality of heavy swine fed different citrus pulp levels

Foi realizado um ensaio utilizando 36 suínos machos castrados, com peso inicial de 83,7±5,1kg, para avaliar o efeito da inclusão de polpa cítrica, 0, 10, 20 e 30%, em um programa de restrição alimentar qualitativa para suínos abatidos aos 130kg de peso, sobre o peso dos órgãos do sistema digestório e sobre características da carcaça e da qualidade da carne. A inclusão de polpa cítrica proporcionou aumento linear (P<0,05) nos pesos do estômago, cólon e fígado, e efeito quadrático (P<0,05) no peso do ceco. Foi observada redução linear (P<0,05) no peso, no rendimento da carcaça e no peso do pernil, porém não houve efeito (P>0,05) sobre o rendimento do pernil. Maior inclusão de polpa cítrica não foi suficiente para reduzir a espessura do toucinho e aumentar a quantidade de carne magra na carcaça, mostrando que a restrição alimentar qualitativa não foi eficiente. Foi observado aumento linear (P<0,05) do pH da carcaça resfriada e linear negativo (P<0,05) sobre as variáveis indicativas de cor da carne em função da inclusão da polpa cítrica nas dietas. A adição de polpa cítrica em programas de restrição alimentar qualitativa não foi eficiente. Por não promover nenhum efeito deletério sobre as características da carne, a polpa cítrica pode ser utilizada como ingrediente alternativo para suínos em terminação.

Ultrathin films of lignins as a potential transducer in sensing applications involving heavy metal ions

Lignins extracted from sugar cane bagasse using different alcohols in the organosolv-CO(2) supercritical pulping process have been applied in the fabrication of ultrathin films through the Langmuir-Blodgett technique. Langmuir films were characterized by surface pressure versus mean molecular area (Pi-A) isotherms to exploit the sensitivity of nanostructured lignin films to metallic ions (Cu(2+), Cd(2+) and Pb(2+)). The Pi-A isotherms were shifted to larger molecular areas when heavy metal ions are present into the subphase, which might be related to electrostatic repulsions between metallic ions entrapped within the lignin molecular structure. Taking the advantage of metal incorporation, Langmuir monolayers were transferred onto solid substrates forming Langmuir-Blodgett (LB) films to be used as a transducer in an "electronic tongue" system to detect Cu(2+) in aqueous solution below threshold standard established by the Brazilian regulation. Both techniques impedance spectroscopy and electrochemistry have been used in these experiments. Complementary, Fourier transform infrared (FTIR) spectroscopy recorded for LB films before and after soaking into Cu(2+) aqueous solution revealed an interaction between the lignin phenyl groups and the metallic ion.

Effect of heavy interstitials on anelastic properties of Nb-1.0 wt% Zr alloys

The mechanical properties of metals with bcc structure, such as niobium and its alloys, have changed significantly with the introduction of heavy interstitial elements. These interstitial elements (nitrogen, for example), present in the alloy, occupy octahedral sites and constitute an elastic dipole of tetragonal symmetry and might produce anelastic relaxation. This article presents the effect of nitrogen on the anelastic properties of Nb-1.0 wt% Zr alloys, measured by means of mechanical spectroscopy using a torsion pendulum. The results showed complex anelastic relaxation structures, which were resolved into their constituent peaks, representing each relaxation process. These processes are due to stress-induced ordering of the interstitial elements around the niobium and zirconium of the alloy.

Assinaturas antropogênicas de elementos maiores e traços em poeira urbana na cidade do Natal-RN

Although there are many studies on urban dust contamination by heavy metals in developed countries, little attention has been paid to this type of study in developing countries, including Brazil. Therefore, a series of investigations were performed to provide signatures of heavy metals in urban dust and assess the potential sources in the city of Natal - RN-Brazil. The fraction of these sediments was studied to pass through a sieve of 63 micrometers. For the study analyzed two groups of samples, one collected in September 2009 at the end of the rainy season (9 samples) and one collected in January 2010 in the dry season (21 samples). So in all, thirty sediment samples were collected from the street. Then, in Fluorescence Spectrometry X-rays were determined major elements SiO2, Na2O, K2O, Al2O3, MgO, P2O5, Fe2O3, MnO, TiO2 and CaO, and trace Rb, Cr, Ni, Cu, Zn, Sr and Pb by an ICPOES was determined Zn, V, Na, K, Ni, Mn, Mg, P, Fe, Cr, Cu, Pb, Ba, Ca and Al from leaching HCl 0.5 mol L-1 . The results of the concentrations of elements show that the greater presence of these occurs in the dry season, except for Si which is higher in the rainy season. Analyses by geoaccumulation Index (IGEO) Enrichment Factor (EF), Contamination Factor (CF), analysis correlation and Hierarchical Cluster, confirm that Zn, Cu and Pb is anthropogenic character. Zinc may be derived from various sources related to motor vehicles or the road signs and street grids. The elements Na, K, Mg and Ca may be related to droplets suspended in air containing cations and anions present in seawater (salty), common in Christmas throughout the year, brought by winds SE-NW. The elements Na, Mg, Ca and K are the most abundant in seawater and were analyzed in this study. This indicates that the source of these additional elements detected by analyzing the contamination factor may be the very sea. Moreover, Ni, Fe, Cr and Ba can be either as a source of anthropogenic geogênica. The source of Ca is different, because it comes in lime and paint (painting guides of buildings and streets) in construction materials, but may also be present in sediments in the fragments of shells or carbonate bioclasts common in the coastal area
